Electrical problem
1984 Chevy Chevette V8 Two Wheel Drive Automatic

Have an 84 corvette, the digital dash was blinking all 8's then went out completely. The instument cluster still has some lights such as the M.P.H. And the R.P.M. Gauges, but both read max even when the car is sitting still. Could this be a instrument cluster issue or is it more likely to be a wiring harness or PCM problem
